# IAM vs 密联

The clearest difference is update cadence: 密联 at fortnightly against IAM's every 4 months. 密联 also leads on iOS requirement (11.0 vs 15.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

IAM ships an update every 4 months, 密联 fortnightly. The most recent releases landed on November 3, 2026 and October 30, 2026 respectively.
